Subject: [Ur] Pre-compressing static assets
Message-ID: <CAC0+czqu3HyaC1-SuasixaNE4cZD1RBJprKSX7xTARq1gPDPZA@mail.gmail.com>

Hey everybody,

I've been breaking my head today on how to do pre-compression of static
assets, mainly the app.*.js bundle. Currently I'm having Nginx do
on-the-fly compression using brotli at lvl 4. This causes my app.*.js
bundle to shrink from 1.8 MB to 145 kB. This is really good already, but
running it at lvl 11 gets me a 90 kB bundle, still 50% less than what I
have now! Running it at lvl 11 takes around 5 seconds (on my underpowered
server) though, which is really quite long.

In a normal situation I'd run the brotli compressor at build or deployment
time, but the app.*.js bundle is never on the filesystem, so I haven't
found a way to do this pre-compression in an Ur/Web context.

Anybody has any ideas?

Simon

I can't think of a good way to do it with Ur/Web as it stands. It should 
be a pretty simple tweak to the compiler to specify an external program 
to run to transform this JavaScript code.

Alrighty, good to know. I'll put it on my list of stuff to do once I dig
into the compiler.

Thanks!
